Explanation:

Step1: Determine the number of electron - pair domains

The molecule has 7 electron - pair domains (7 F atoms bonded to the central atom).

Step2: Relate electron - pair domains to hybridization

The formula for hybridization is based on the number of electron - pair domains. For \(n\) electron - pair domains, the hybridization is \(sp^{n - 1}\). Here \(n=7\), so \(sp^{7 - 1}=sp^{3}d^{3}\)

Answer:

\(sp^{3}d^{3}\)
